摘    要:针对YKS规格的高压高速电机单机容量高、局部温升大等特点,以1台YKS5602 3 000 kW规格的高压高速电机为例,依据电机实际尺寸,建立了电机端部绕组及定转子模型。采用有限元法对流体场与温度场进行了仿真,计算出电机运行时各个通风槽内冷却气体流动情况,并对电机整体进行流固耦合分析,得到高压电机端部绕组及定转子温度场分布。对仿真计算结果分析,并与样机试验数据比较,结果表明:流体场和温度场耦合的方法能够准确地了解YKS电机各个通风槽内的气体流动情况及电机内局部温升分布。

关 键 词:高压高速电机   流体场   温度场   耦合分析

Abstract:YKS series highvoltage and highspeed motor had the characteristics of high single unit capacity and large local temperature rise. A YKS5602 3 000 kW highvoltage and highspeed motor was taken as an example. According to the actual size of the motor, the motor end winding and statorrotor models were established. The finite element method was used to simulate the fluid field and temperature field. The flow of cooling gas in each ventilation slot was calculated during motor operation. The fluidsolid coupling analysis of the whole motor was carried out to obtain the temperature field distribution of the end winding and stator of the highvoltage motor. The simulation results were analyzed and compared with the experimental data. The results showed that the method of coupling the fluid field and temperature field could accurately acquire the gas flow in each ventilation slot of the YKS motor and the local temperature rise distribution in the motor.
Keywords:highvoltage and highspeed motor   fluid field   temperature field   coupling analysis
